Fresh details have emerged about what police found inside the home of accused mushroom murderer Erin Patterson last year.

Australian Federal Police commissioner Reece Kershaw revealed the information at a Senate estimates hearing in Canberra on Tuesday night.

Among the items found were five iPads, two secure digital cards, a smart watch and a trail camera.

The search took six hours at the Leongatha home, two hours south-east of Melbourne, and occurred the morning Patterson was charged with three counts of murder and five counts of attempted murder.

“Technology detector dog Georgia found one USB, a micro secure digital card and a SIM card,” Kershaw said.

“Technology detector dog Alma found a mobile phone, five iPads, a trail camera, and secure digital card and a smart watch.

“These were not found during initial searches undertaken by officers.”

The 49-year-old mother-of-two remains in jail with police having a 20-week adjournment to build their case against her. This is due to be served on March 25.

Erin Patterson, who faces three charges of murder and five of attempted murder.

Heather Wilkinson, 66, her sister Gail Patterson and brother-in-law Don Patterson, both 70, all died after the meal on July 29.

Wilkinson’s husband Ian, 68, spent close to two months in hospital critically ill and is still in recovery.

Erin Patterson’s two children were at home during the lunch but did not eat the same meal.

Her ex-husband was reportedly invited to dine but did not attend.

Victoria Police released a statement at the time the charges were laid saying the investigation had been “incredibly complex, methodical and thorough”.

Detective Inspector Dean Thomas also urged against “unnecessary speculation” and sharing “misinformation.”

“Over the last three months, this investigation has been subjected to incredibly intense levels of public scrutiny and curiosity,” Thomas said.

“I cannot think of another investigation that has generated this level of media and public interest, not only here in Victoria but also nationally and internationally.

“I think it is particularly important that we keep in mind that at the heart of this, three people have lost their lives. These are three people who by all accounts were much beloved in their communities and are greatly missed by their loved ones.

“These deaths and incidents also continue to have a significant impact on the immediate families of those involved and I ask that people are particularly mindful of this over the coming days.

“Today’s charges are just the next step in what has been an incredibly complex, methodical and thorough investigation by Homicide Squad detectives.

“I know that people will no doubt have many unanswered questions about this matter, however I urge people to be especially mindful of unnecessary speculation and not sharing misinformation.”

Patterson has protested her innocence in the past.

In an earlier statement to police obtained by the ABC, Patterson said she made a beef Wellington using button mushrooms from a major supermarket and dried mushrooms bought at an Asian grocery store.

She said she ate a serving and later suffered bad stomach pains and diarrhoea, contrary to the suggestion of detectives that she did not fall ill.

Police have not commented on Patterson’s statement other than to say it was not one taken by officers.

Hundreds of people attended public memorials for Wilkinson and Gail and Don Mr Patterson, who were remembered for their commitment to their families and tight-knit community in Korumburra.
